Material examined. 1♂ (CASENT 9037134): HUNGARY: Pest County: Remeteszőlős, Remete Mountain , 3.X.2007 (G. Kovács) .

Diagnosis. As already pointed out by Řezáč et al. (2008), the males of this species can be recognized by the relatively small lamellar groove and terminal tooth ( Fig. 23 ). Also, the males have a relatively flat pars cephalica in front of the PMEs, only slightly elevated ( Fig. 30 ), and a globular bulb ( Fig. 23 contra to E. walckenaeri Fig. 25 and contra to E. moravicus Fig. 24 ), with the conductor having a steeply elevated lamella ( Fig. 23 ).

Description. See Řezáč et al. (2008).

Distribution. Europe, Turkey, Caucasus, Russia (Europe to Far East), Iran, Central Asia ( World Spider Catalog 2020).
